Let there be light

Daylighting systems provide a myriad of benefits to building occupants and can increase profits

It's no secret people prefer to be in a well-daylit environment as opposed to one that relies solely on electric light sources. According to the Mayo Clinic, Rochester, Minn., the amount of daylight we receive affects our brain chemistry and a lack of it can lead to seasonal affective disorder. People are happier in a space that offers comfortable, reliable natural daylight.

In addition to improving people's moods, installing daylighting systems can increase your profits while saving your customers money by reducing the reliance on electric lighting.


Buildings with properly designed daylighting and integrated lighting controls generate energy savings as a result of not powering the lights all day. Depending on where a building is located, it is realistic to daylight a space 60 to 90 percent of the occupied year, assuming typical 8 a.m. to 5 p.m. operating hours. According to a Buildings magazine article, "What You Need to Know About Daylighting," the energy savings for buildings with daylighting systems typically range from 15 to 40 percent.
